Abstract (en)
[origin: WO2009092084A1] A drug delivery device (10) is provided herein, the device including a reservoir (12) for containing a medicament The medicament includes a suspension of solids in a liquid carrier The device also includes a needle (38) having a distal end (42) for injection into a patient, a proximal (40) end in communication with the reservoir, and a lumen (44) extending between the distal and proximal ends A path (60) is defined from the reservoir to the distal end of the needle through the lumen, the path having an inner diameter that decreases in the proximal to distal direction along at least a portion thereof Advantageously, with the subject invention, a flow path may be defined which provides a more gradual transition in diameter from the reservoir to the distal tip of a needle In this manner, changes in velocity of the suspension may be less abrupt than m the ppior art, thus better maintaining solid particles in the suspension.
